Sound quality impact - preamp vs power amp?

They are so much different tubes amplifiers , they are so much S.S. amplifiers also...

They are so much different pre amp and different power amp....

How can one may devise a solution or a choice applicable to all?

In audio all these debates and wars about tube/ S.S. or digital/vinyl, power amp/pre-amp, are meaningless because there is not one choice applicable to all...

In audio tough there is a rule universally applicable:

We must learn how to control and treat any audio system mechanically, electrically and acoustically...

This is the key for the creation of real audio experience....Any other solution which pretend to be the best solution for all ,is only  fetichism, habits, marketting conditioning, tastes, money throwing, ignorance.... Sorry....

Happy new year for all of us....A better year will be great....😊

hilde45 Interesting observation and something i dont have difficulty to figure out....

If i upgrade my audio system i will buy a Berning ZOTL tube amplifier that can also work like a pre amplifier with my Sansui AU 7700 which can work like a separable or like an integrate power and/ or pre-amp....(Sansui Au 7700 is one of the more flexible amp ever designed )

For this reason : tube for pre amp and S.S. for power amplification...

I feel no urge because the pre-amp section of the Sansui Au 7700 is already very good... For sure the Berning ZOTL would be better tough....

Merry Christmas...
